People mainly identify orthodontics with braces. But while they’re a major part of it, braces aren’t the only way this important dental specialty can make a difference in a person’s bite.
For example, orthodontics can help guide the development of a younger patient’s facial structure that could head off future upper teeth misalignment. The area of focus is the upper jaw and palate (the roof of the mouth) that jointly make up a structure called the maxilla. The maxilla is actually formed by two bones fused together in the center of the palate along what is known as the midline suture running from front to back in the mouth.
The two bones remain separated until puberty, which helps accommodate rapid structural growth during childhood. But problems can arise if the upper jaw is too narrow, causing a “cross-bite” where the lower back teeth bite abnormally outside the upper ones. This can crowd upper permanent teeth and cause them to erupt improperly.
Using a technique called palatal expansion we can correct this abnormality if we act before the maxillary bones fuse. The technique employs a custom-made appliance called a palatal expander that attaches to the posterior teeth of the upper arch. Expanders have two halves joined by a small screw device to increase tension against the teeth to widen the jaw. A parent or the patient (if old enough) increases the tension by using a special key to turn the adjustment screw a tiny amount each day. This may cause minor discomfort that normally eases in a few minutes.
The patient wears the device until the jaw expands to the desired width and then allows the bones to stabilize in the new position. This can sometimes create a small gap between the upper front teeth, but it often closes on its own or it may require braces to close it.
While palatal expanders are not for every case, they can help normalize development and improve the bite, and thus preclude more extensive orthodontic treatment later. But time is of the essence: after the maxilla has fused, surgery will be necessary to separate them and widen the palate. It’s important then not to delay if your child could benefit from this effective treatment.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?
Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?
Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.
Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.
But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?
In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.
Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.
What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.
If you have a gap in your grin — whatever the cause — contact us or schedule an appointment for a consultation, and find out which tooth-replacement system is right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Crowns & Bridgework.”
